最新研究表明, 發現正確的事實可以讓陰謀論者產生懷疑,而人工智能正是可以從旁協助的工具。在與人工智能模型GPT-4 Turbo 進行基于證據的對話后,陰謀論者大大降低了他們對所青睞的陰謀論的信任度,而這種新萌生的懷疑態度持續了數月。如此大規模揭開陰謀論信仰網絡的舉措在以前是無法實現的。

After an evidence-baseddialogue with GPT-4 Turbo, anAI model, conspiracy theoristssubstantially reduced their beliefin favored conspiracies, and thisnewfound skepticism remainedfor months. Unraveling webs ofconspiracy beliefs at scale hasnot previously been possible.

封面圖展示的這張照片是一只雌性標準花鼠——一種用于寵物貿易的馴養變種。考慮到老鼠與人類之間長期的密切關系,老鼠成為很好的寵物也就不足為奇了。雖然棕色和黑色的“野生”老鼠確實會傳播一些傳染病,但近期我們了解到它們具有一些更積極的屬性,包括它們技巧熟練、適應性強,甚至很喜歡玩耍。

帕帕哈瑙莫夸基亞海洋垃圾項目(PMDP)的技術人員從西北夏威夷群島的珊瑚礁中回收了大量廢棄的漁具。一項新研究表明,經過數十年從海洋和陸地棲息地清除危險塑料垃圾的不懈努力,瀕危的夏威夷僧海豹被塑料纏繞的概率已經被成功降低了。

兩個研究小組重點研究了肺炎克雷伯菌的防御相關逆轉錄酶系統,發現了滾環逆轉錄的機制。當噬菌體感染后,所產生的串聯互補DNA 會轉化為雙鏈DNA,導致轉錄出幾乎無限的開放閱讀框架(簡稱neo)mRNA, 該mRNA為一個Neo 多肽編碼。這些研究強調了可以通過以RNA 為模板的基因創建擴展基因組編碼的潛力。
